CARRIER FOR. PNEUMATIC-TUBE APPARATUS.

Specification of Letters Patent.

Patented Dec. 10, 1907.

M ni al. filed a... 29,1905. Serial No. 267.548.

To all whom it may concern:

Be it known that I, EDMOND A. FORDYOE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Carriers for Pneumatic-Tube Apparatus, of which the following is a specification.

My invention relates to improvements in carriers for pneumatic despatch tube apparatus, and its object is to produce a carrier that is provided with meansfor keeping the rear open end in the shape of a ring so that this open end is kept distended thereby giving the carrier the full benefit of the atmospheric pressure behind it.

In the accompanying drawirigs which illustrate a construction embodyin I my invention, Figure 1 is a side view 0 the carrier with part of the rear end broken away to show construction. Fig. 2 is a cross sectional view on the line 2-2 Fig. 1. Fig. 3 is a detail view of the metallic ring. Fig. 4 is a sectional view of part of the leather cover. Fig. 5 is a detail sectional view of the ban around the rear end of the carrier. 1

Like letters of reference refer to like parts throughout the several views.

' A represents the shell of the carrier usually made of leather and B is the usual buffer head which travels in advance as the carrier is sent through the system owing to the vacuum ahead and the atmospheric pressure behind it.

O is the inner cloth lining and D the outer leather cover. In the rear end of the leather cover there is a depression E in which is adapted to be sprung the metal ringF. Over this ring and secured to the leather cover D and lining O by two rows of stitching is the leather band G for the purpose of stiffening the rear end and at the same time to prevent the metallic ring from being displaced. By this construction the rear end of the carrier is kept distended and always fills the tube, so that the atmospheric pressure behind it has full force and, cannot escape around the carrier.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A carrier for pneumatic despatch tube apparatus having an outer body provided.

at its rear end with a recess, an inner lining for said body, a metallic ring adapted to fit said recess and hold the rear end open and ring-shaped, and means secured to said body for preventing displacement of said ring.

2. A carrier for pneumatic despatch tube apparatus having an outer body provided at its rear end with a recess, an inner lining for said body, a metallic ring adapted to fit said recess and hold the rear end open and ring-shaped, and yielding means secured to said body for preventing displacement of said ring.

3. A carrierfor pneumatic despatch tube apparatus having an outer body provided at its rear end with a recess, an inner lining for said body, a metallic ring adapted to fit said recess and hold the rear end open and ringshaped, and a leather band secured to said body for preventing displacement of said ring.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 20th day of June A. D. 1905.
